Nitrate

Monitor Nitrate with Xylem Analytics

Nitrate (NO3-) forms in water when bacteria use dissolved oxygen to oxidize ammonium. Nitrate is mobile and may seep into streams, lakes and estuaries from ground water enriched by animal or human wastes or commercial fertilizers. High concentrations of nitrate can enhance the growth of algae and aquatic plants.

The Xylem YSI Nitrate Sensor consists of a silver/silver chloride wire electrode in a custom filling solution. The internal solution is separated from the sample medium by a polymer membrane, which selectively interacts with nitrate ions.

The new multi-parameter systems with intelligent, digital sensors for pH, dissolved oxygen (DO) and conductivity measurement revolutionize multi-parameter measurement:The signal processing is completely located in the sensor, and the measuring signal is transmitted to the meter without interference and in a clearly identifiable manner via thin, highstrength cables. A wide range of sensors are available for virtually every application.

Capturing accurate data in fresh water, ground water and marine aquatic environments is easy with the versatile multiparameter EXO1 sonde. Ideal for estuarine, surface water or ground water applications.Instrument Only. Cables, probes/sensors, and accessories sold separately - please see the "Accessories" tab for details.

The EXO advanced water quality monitoring platform includes the versatile multiparameter EXO2 sonde for oceanographic, estuarine, or surface water applications. Collect data to 250m with the advanced EXO2 sonde – contains six replaceable 'smart' sensors and a central wiper to clean biofouling.

Each TruLine ISE features an integrated reference. This eliminates the need for a separate reference half-cell when measuring ion concentration and is more convenient. Each ISE can be refilled with reference/electrode filling solution, extending the life of each ISE. The electrodes also feature a double-junction reference for optimum performance in the lab.
